` PULLING-OVER MACHINE.

Specification of Letters Patent.

Y.'iimiicaemn mea May a, 1913. serial No. 765,057.

To all whom t may concern Be it known that I, ANeELo PERM, a citizen ofthe United States, residing at Haverhill, in the county of VEssex andState of Massachusetts, have invented certain Improvenients inPulling-Over. Machines, of

which the following description, in connection `with the accompanyingdrawings,is a specification, like reference characters on the drawingsindicating like parts in the several figures. Y A Y This inventionrelates to shoe supporting means for pulling-over -and other upperstretching or shaping machines and is herein shown as embodied insupporting means for a pulling-over machine suchpas is shown in UnitedStates Letters Patent No. 1,029,387, granted June 11, 1912 on anapplication of Ronald F. McFeely.

An object of this invention, among others, is to provide last supportingmeans which will contribute to the operation performed by these machinesof shaping the upper to the last. As herein shown theV last supportingmeans embodying this invention serves this purpose by engaging the upperon the top of the forepart of a shoe at opposite sides ofthe middleportion of the shoe and Y moving to stretch the portion of upper locatedbetween the engaging points. It also serves the upper shaping purpose byengaging the upper on the top of the forepart of a last at or near themiddle ofA the last and forcing the upper against the last in the hollowor depression whichis `usually Vfound between the instep and the toe ofthelast, particularly if the last has a high toeior prominent toe. Inboth of these ways this invention assists in overcoming the very commondiiiiculty experienced by the upper bridging across this depression fromthe instep to the toe. This invention may be embodied in mechanism whichoperates to shape the upper either by pressureor by stretching inthe'way above indicated as well as in such mechanism as that hereinshown which operates to shape the upper in both of these ways. Y Y

An important feature f of this invention consists in last supportingdevices arranged to engage the top fof the forepart of a shoe and to bemoved apart in response to last supporting pressure for stretching thestock that is located betweenthermor it may beby movement producedautomatically or otherwise after they have contacted with the shoe andbefore they come into rmlast supporting relation to the work.

Patented nee. a, 1era Another feature of this invention consists i in alast support and means for moving it intoa position opposite to the topof the last and then for moving it into supporting engagement with thework.

These and other features of the invention will appear and be more fullyunderstood in connection with the following description of a preferredembodiment of the invention and will then be pointed out in the claims.

Referring to the accompanying drawings,

Figure 1 is a view, partly in elevation and partly in section, of somuchof a pullingover machine of the type shown in said prior Letters Patentas is necessary for illustrating this invention.

Fig. 2 is a similar View of the parts shown in the lower portion of Fig.1 showing the changed relation ofthe parts brought about as theoperation of the machine progresses.

Fig. 3 is a side elevation of the toe portion of a shoe being pulledover illustrating the manner in which the upper bridges between theinstep of the last and a high toe.

The sole-rest 2 and its operating mechanism, the i grippersV 4 and theiroperating mechanism, and the tackers 5 and their operating mechanism areor may be the same as shown and described in said patent, as may alsobethe general construction of the side clamp arms 6 and the operatingmechanism therefor. The rubber covered side clamp lblocks 8 are mountedVto adjust themselves angularly to the requirements of individual shoes,but have no yielding movement outwardly upon the arms 6 such as theyusually have heretofore had.

The last supporters are carried by slides 10 which are guided forhorizontal movement in blocks 12 secured rigidly to the side clamp arms6. A spring 13 holds each slide pressed inwardly toward the median lineof the machine. Each last supporter 20 is mounted on a carrier 15 whichis pi'voted to the slide 10 to swing about a substantially horizontalaxis andrests upon the inner end of a lever 16 which is pivoted to theblock 12 and can turn about an axis located at 17 but isnormally heldwith its inner end upraised by means `of a spring 18. An adjustablestopV screw 19 carried by the lever and abutting lar position shown in Fig. 1.V

In the operation of the machine the cycle afl-whichmaybe-1n general asset forth 1n said prior patent, the arms@ are moved toward each" otherkfor clamping the upper and.V upholdmg the shoe for the upper securingtacks to be Vinserted after the grippers have given place to-the tackers5. As the arms 6 move toward each other the adjacent end faces of thecarriers l5 engage one another,

the last supporters -20 being at such time located below the shoe andout of touch therewith and each in the` angular position represented inFig. 1. After such engagement of the carriers 15 with one ane-ther theyyield withrelation to the blocks 12 against the resistance of thesprings 13. The lower faces of the carriers 15 are inclined as Shownwhereby said carriers constitute in effect wedges located betweenthefront arms of the levers 16 and the last supporters 2O and,therefore, as the carriers yield outwardly' in the blocks 12 they areforced upwardly, moving about their pivotal connections with the slides10 and therefore carrying the last supportersZO apart as they riseindicated by t ie lower` arrowsin Figa-2'. By

theupward movement of the last supporters against the shoe they pressthe upper into engagement with the last at the place where the upper ismost likely to bric ge between the instep and the toe of the last,particularly if it is a high-toed last. During the described pivotalmovement of the last supporters in the direction indicated by the lowerarrows in Fig. 2 they rub or stretch the upper toward opposite sides ofthe last as indicated bv the arrows on the last in Fiff. 2, thussupplementing the action of the grippers which preferably are at thistime still pulling upon the upper. ln thesev ways the last supporterscooperate with the grippers to conform the upper to the last and tightenthe` upper to a very substantial extent. :When theA lastV supporters areturned into the position shownrin Fig. 2 and the carriers 15 can bemoved no farther upwardly, the s upporting levers 1G thereatter yieldagainst Vthe action of their springsjlSlto permitthe side clamp'arms 6to continue andfcomplete their stroke for bringing the 'clamp blocks 8into engagement with the shoe at the edge ofthe last bottom. lt is to be.noted that the upper tightening action of the last supporters takespla'ee prior to the engagement Vpletion of themovement'ofthe arms6,-s'aid' blocks will be made to cla-mp the" upper firmly to the sidesof the last after which the incoming backers-5 willfftr-ip the-,guip-`pers and cause the wipers located on the lower faces of the taekers tolay "the `upper into position to betacked. It will be noted` that thesupporting connections for the last. supporters f 20 are so varranged asto afford substantiallyrigid upholding of thev shoe against the impactof the tack drivers.
